PHILADELPHIA – The report on Pedro Martinez was still undetermined last night.

Martinez was in New York yesterday at the Hospital for Special Surgery being examined. Just before the Mets’ 11-4 loss to the Phillies last night, PR man Jay Horwitz reported that Dr. Struan Coleman was still looking at Martinez’s results and there would not be more of an update until today.

In Monday night’s 13-0 loss, Martinez pitched one inning against the Phillies, as he experienced a strained right calf. The Mets said Martinez had the problem during his pregame warm-ups.

“He spoke to [trainer] Ray Ramirez earlier [yesterday] and said he felt a little sore, but he didn’t seem alarmed by it,” Willie Randolph said yesterday. “But I’ll just kind of wait and see what the MRI says before I give you guys a heads-up on what’s going on.”

Martinez left Philadelphia for New York on Monday night, and regardless of how the tests were to go, Randolph said he did not know if the pitcher was going to rejoin the team here.

The manager, however, said he was “not concerned at all, really.” He also was unwilling to discuss what the Mets might do Saturday when Martinez is next supposed to be on the mound.

“Way too early,” he said. “Let’s find out how he’s feeling first.”

If the Mets bring up a starter, the potential candidates could be Triple-A pitchers Mike Pelfrey, Oliver Perez, Brian Bannister and Jose Lima. Pelfrey is on the seven-day DL with a right lat muscle strain, though he has told The Post he could come back “sometime next weekend, maybe Saturday or Sunday.” Darren Oliver could also be a contender.

“[Martinez] might just say, ‘Listen, I feel fine,’ and he’ll take the ball his next start,” Randolph said. “But it’d be real easy for us to go to Plan B if we have to. We’ll just look to bring somebody else up.”

Martinez was out for a month earlier this season with an inflamed right hip.

According to one source, Diamondbacks right fielder Shawn Green wants to be moved out of Arizona and is believed to be OK with joining the Mets.

However, someone with knowledge of the situation told The Post on Monday that for Green to be a Met, he not only would have to waive his no-trade rights (he has a no-trade clause for all teams but San Francisco, Anaheim and San Diego) but the Diamondbacks would have to hand the Mets plenty of cash for Green’s 2007 contract.

The Mets released Eli Marrero yesterday. They had designated him for assignment last week.
